I see you mention that you're targeting Android 13 but can you double-check? I've had other reports and they let me know that targeting Android 13 fixed it for them.

Xamarin.Essentials 1.8 now has MonoAndroid13 as the target framework, your project should do the same :) that means you should also target API 33. See detailed instructions in this blog post.

After you have updated the target framework you might want to do some aggressive cleaning and rebuilding and maybe even delete your bin/obj folders to make sure nothing is left behind building against MonoAndroid10

That was it, thanks. UI showed using SDK version 13 (which I think is read/written from the manifest), but TargetFrameworkVersion in csproj was still set to 12.

Thanks for letting me know! I did update the GitHub releases here to make this a little more clearer as well.
